I completed my install this past weekend. The look is better and probably what most of us are after. I haven't logged enough miles to determine handling, I know the trucks handling limitations have a lot to do with things other than springs, but I hope to address those in the near future. I am also looking forward to how it handles towing since lowered.
A few notes about the install I learned as I went through it all. Eibach does not supply directions so I used the MOPAR spring install directions to get all the torque specs needed. They also do NOT supply new nuts for the front struts. I had to get new ones, nylon fasteners should only be used once. Spring ends do not line up where the factory springs did exactly, just be sure to index everything before disassembly.
